This is mostly due to the climate conditions before the growing season, which influence the rate of evapotranspiration and subsequent plant growth. [69] The expansion of the Gobi is attributed mostly to human activities, locally driven by deforestation, overgrazing, and depletion of water resources, as well as to climate change. [68]
For instance, it might be difficult to tell if desertification or desert expansion is the result of climate change or human activity. [19] Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers.
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
[239] [240] Climate change increases the intensity and frequency of extreme weather events. [240] [241] It can affect transmission of infectious diseases, such as dengue fever and malaria. [238] [239] According to the World Economic Forum, 14.5 million more deaths are expected due to climate change by 2050.
Rising temperatures, intensified droughts, declining precipitation, desertification, salinization, and the increasing prevalence of dust storms are challenges Iraq faces due in to the negative impacts of climate change.
But as climate change makes heat waves more frequent, intense and long-lasting, experts say the increasingly severe conditions are testing some iconic desert plants known for their resilience ...
Desertification is one of the issues of environmental concern in Nigeria, particularly the northern part of the country. According to UNEP [4] in 1993, Northern Nigeria has one of the highest rates of deforestation in the world at about 3.5%, caused by land degradation, increase in agricultural intensity, over-grazing of livestock, and demand for fuel by cutting down trees.
